Nancy Guthrie live updates: Family cleared as suspects, Savannah Guthrie issues plea to possible abductor

The search for Guthrie is continuing, with investigators pursuing leads after a recent court-ordered search did not result in any arrests.

Two sources familiar with the investigation told NBC News that authorities are leaning away from the man whose home was searched Friday night as a suspect. Investigators are also leaning away from a man named Carlos, who was stopped in a car earlier this week, as a suspect, the sources said.

In addition, investigators are leaning away from any relatives of Guthrie as suspects, according to the sources. They cautioned that no one has been officially ruled out, and investigators continue to focus on other leads.

Investigators are also not categorizing the case as any particular type of crime at this stage, according to a federal law enforcement source with knowledge of the investigation. 

The source said that there are a “myriad of theories” but that authorities are not officially narrowing options to a specific one.
